BALLAST
CONDITION:
The Displacement type separator, after the initial water fill, is ready to receive
a product spill. Note optional disposal of water effluent by gravity flow or by
pumping. |
 |
RESIDENT
CONDITION:
The Displacement type separator is illustrated after sufficient oil has accumulated
to produce an equilibrium resulting from the weight differential of the oil-water mixture
in the separation chamber, and the water in the water holding sump. Subsequent additions
of either oil or water will displace like amounts into either the oil or water sump.
The "last-in, last-out" operation allows full utilization of the time interval
between spills for gravity separation. |
 |
MAJOR
HYDROCARBON SPILL:
The patented design allows catastrophic release of oil to be contained in the separator.
Once the dedicated oil sump is full, the oil spill depresses the water ballast in the
separation chamber. Since the weight of the oil cannot overcome the weight of the water
in the transfer pipe, the vessel hydraulically "locks-up" containing the spill
and preventing a release to the environment. |
 |
OIL
STOP VALVE:
This patented design check valve eliminates the chance of contamination of the
effluent stream by shutting off flow in the event of an emergency hydrocarbon spill. |
|
|
FREEZE
PROTECTION:
Electric immersion heaters or stem coils can be installed to insure flowing temperatures
in the vessel when located above ground or above frost line. |
|
COALESCING
OPTIONS :
For enhanced gravity separation requirements, the ENQUIP Gravity Displacement Separators
can be supplied with coalescing media. |
|
THE
MESH PAK™:
A removable bundle of high density polypropylene wire mesh contained in a stainless
steel carrier. The oleophilic properties of the mesh allow oil particles to agglomerate
to a size sufficient to hasten their rise to the interface. |
|
|
THE
PLATE PAK™:
A parallel series of carbon, stainless or fiberglass plates inclined to 45°,
which provide increased surface area and direct oil particles toward the oil-water
interface. |
|
| The configuration
of either system provides a sludge retaining baffle which keep accumulations
of sediment from reaching the separation compartment. |
 |
NUSTYLE:
The configuration orients the separation chamber at one end of the vessel and allows
a straight-through flow of water. Flow losses through the shorter transfer pipe are
reduced. Additionally, inlet and outlet piping runs are generally more convenient
since entry and exit are on the opposite ends of the vessel. NOTE: Segregated
oil and water sumps allow for automated pump systems if necessary. |
DOUBLE
WALL CONSTRUCTION:
A full 360° wrap outer shell constructed of 1/4" thick carbon steel is added
to meet secondary containment regulations. Interstitial monitors are available to detect
water or hydrocarbon intrusion into the annular space. |
